NICER sees the contraction of the corona in a black hole X-ray transient(14 Jan 2019)
NICER made the cover of Nature with an analysis by Kara et al. of the temporal behavior of the X-ray spectrum of the black hole transient system MAXI J1820+070. Their analysis of the time-resolved NICER spectra of this system showed that the inner edge of the accretion disk is near the accreting black hole and that variations in the X-ray spectral lags indicated that the corona shrank over a time interval of a few weeks.
